The embodiment of the invention provides a power supply system and engineering machinery, and belongs to the field of engineering machinery. The power supply system comprises a get-on power supply system, a get-off power supply system, a vehicle control unit and a conducting ring device, the vehicle control unit is used for controlling the power supply state of the upper vehicle power supply system and the power supply state of the lower vehicle power supply system. The power supply state of the upper vehicle power supply system comprises a non-operation power supply state; and the get-on power supply system is used for supplying power to the get-off power supply system through the conducting ring device in the non-operation power supply state. According to the invention, the get-on powersupply system and the get-off power supply system are used for combined power supply, and the problem of short endurance mileage can be solved.
